COMBINED CHURN AND BUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 564,978, dated August 4, :1896.

Application filed October 25, 1895.

T all 107mm/ it 'may concern..-

Beit known that I, LEVI A. DISBROW, a' citizen of the United States, residing at Owatonna, in the county of Steele and State of Minnesota, have invented certain new andv useful Improvements in a Combined Chnrn and Butter-Worker; and I do hereby declare the following to be a full, clear, and 'exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide an improvement in combined churns and butter-workers. The machine is especially designed to be operated by power, for use in creameries, but may of course be made of a size suitable for operation by hand. The machine may also be applied for other purposes, such as kneading dough or other plastic materials.-

To the end above noted my invention consists of the novel devices and combinations of devices which will be hereinafter described, and deiined in the claims.

My improved machine is illustrated in the accompanying drawings, wherein, like letters referring to like parts throughout-- Figure l is a side elevation of the complete machine. Fig. 2 is a View, chielly in rightend elevation, but partly in section, on the p line at' of Fig. l. Fig. 3 is a detail in section on the line x2 r2 of Fig. l with some parts broken away. Fig. at is a horizontal section through the entire machine on the line :1:3 m3 of Fig. 2. Fig. 5 is a vertical cross-section on the line :r4 @ci of Fig. 4.

a represents the floor-line in a building. c. represent uprights, and a2 a3 horizontal pieces connected thereto,which parts together constitute end frames, in which the working parts are mounted.

The drum-body b is provided on its interiorwith inwardly-projecting radial cleats b', of angular form in cross-section, and is closed at both ends by tight heads b2. The cleats b extend near to but stop short of the heads b2 and are beveled at their ends, so as to form an inwardly-flaring annular space b3 between the ends of the cleats b and the heads b2. The

`altogether in the churning action'.

Serial No. 566,824. {No model.)

4bod y of the drum or cylinder is provided with 5o a door b4, adapted to be locked in its closed or working position by eccentric clamps b5 in the usual or any suitable way.

To the drumheads b2 are bolted or otherwise secured central disk-like castings h6, which are provided with hollow journals or gudge'ons bl, extending through the drumheads and mounted in suitable bearings bs, fixed to the frame-pieces (4.3. f

Vithin the gudgeons are mounted the 6o 'hollow axial arms b9 of crank-like hangers 69h10, the other or radial arms Z110 of which hangers are located within the drum. To the radialarms blo of said crank-like hangers is journaled the outer or idle member b of a pair of working rollers b 1712. The journals 1113 for the said' idle-roller?)11 are shown as `formed by headed screws working through Asuitalole passages in the hanger-arms bw and pieces a3 on opposite sides of the axis of the 8o kdrum as shown in Fig. 4.

The gudgeons t7, the axial arms b9 of the crank-like hangers, and the central shaft b are provided with registering sections of a common pinhole b, into which the pin h1 85 may be inserted to lock the crank-like hangers b9 b1 and the central shaft bs to the drumgudgeons o7 for a common rotary movement Then the pins b1 are applied, as shown in Fig. 4, 9o the crankdike hangers b9 blo will be held stationary in respect to the rotary movement ol the drum, which is the relation sustained by the said parts when working the butter, as will presently more fully appear.

The crank-like hangers b9 bm are covered inside the drum by radial wooden shields or covers Z218, which are constructed to fit over the radial arms Z910 of the said hangers, as shown in Figs. 4 and 5. The said covers Z210 are of an area to extend beyond the rollers Z211 Z212 in every direction and are provided with outwardly flaring or beveled surfaces Z219 on their rims, which work within the reversely-flaring annular spaces Z23 between the cleats Z2 and the drumheads Z22.

In the covers Z918, above the central roller Z212 and on the side of the same opposite to the roller Z911, is mounted an idle-roller Z220, for purposes which will presently appear. The working rollers Z211 Z212 are corrugated. The idle-roller Z920 is preferably smooth.

The action or operation of the parts so far described will be stated after specifying the parts of the drive employed.

To the right-hand drumhead Z92 is bolted or otherwise fixed a large crown-gear casting c. With the same engages a pinion c on the inner end of a main driving-shaft c2. The said shaft c2 is journaled in suitable bearings c3 c4, fixed, respectively, to the main framepiece a3 and to a pedestal-casting c5, fixed to the floor of the building. Another and smaller pinion o0 also constantly engages with the crown -gear c of the drumhead. The said pinion a0 is carried at the inner end of a counter-shaft c1, mounted in a depending bearing-braoket e0, fixed to the frame-piece a3, and in a bearing o0 on a short pedestalcasting C10, fixed to the floor inward of the pedestal c5. The said counter-shaft c7 is provided with a gear c11, adapted to be engaged by a shifting gear 012 on the projecting end of the central shaft Z214, which carries the working roller Z212. Outward of the gear 011 the counter-shaft c1 is provided with a gear C15, which constantly engages with a pinion C11 on a common hub with the half member C15 of a friction-clutch, which is loosely mounted on the main shaft o2. Another half-clutch member 010 is fixed to the shaft c2 and spaced apart from the half-clutch 015. Between the clutch melnbers 015 and n10 is loosely mounted on the shaft c2 a constantly-running doubleclutch surface-pulley 011. The pulley 011 is subject to the action of an armed shipperfork sleeve 01S, mounted for sliding motion on the shaft c2, the arms of which extend through the half-clutch 010 and engage over a suit-able collar in the hub of the pulley 017.

The slee ve 018 is operated by a shipper-fork lever C10, of any suitable construction, but shown as of bell-crank form, pivoted to the outside pedestal c5. The clutch-surfaces are all friction-surfaces. The members 015 and C10 are spaced apart sufficiently far to render the loose pulley C17 idle when in its central position. Hence through the shipper-fork the pulley C11 may be thrown into frictional engagement either with the clutch member c15 or the clutch member C10 at will. lf the pulley c11be in engagement with the loose clutch member 015, as shown in Figs. l and -t of the drawings, the counter-shaft c7 will receive motion therefrom through the pinion c11 and the gear 013, and the churn drum or cylinder will be rotated with slow motion, as

is desirable for working the butter; and if the shifting gear C12 on the shaft Z211 be in mesh with the gear C11 on the counter-shaft c1, as shown in Figs. l and 4, the central working roller Z212 will be positively driven from the counter-sh aft. In this butter-working action the bottom of the drumwill be moved from the right toward theleft. On the other hand, if the loose pulley c1T is thrown outward by the shipper-fork, so as to en gage with the fixed half-clutch member 010 and the shifting gear 012 be thrown out of engagement with the gear C11 on the counter-shaft, then the main shaft c2 will become operative to rotate the drum at a relatively. high rate of speed, as is required in the churning action When churning it is of course necessary or desirable to first pin the crank-like hangers 120 Z910 and the shaft Z211 fast to the drum-gudgeons Z27 after the lever-arms Z915 have been released from the framework by the removal of the pins Z910. The working rollers Z911 Z212 and the idle-roller Z220 would then all be locked fast to the bottom of the drum, and the drum would be rotated from left toward the right with reference to Figs. 2 and 5 until the churning was completed. The loose pulley would then be shifted inward to engage with the loose half-clutch G15 after the pin had been removed from the hole Z917 and the lever-arms Z915 had been pinned fast to the framework, and the drum would then be rotated in the reverse direction, or, as shown by the arrows in Figs. 2 and 5, at a relatively slow rate of speed but with correspondingly-increased power as required to work the butter. After the lever-arms Z915 were pinned fast to the framework, the crank-hangers Z29 Z210 would become stationary relative to the motion of the drum and would hold the working rollers Z211 Z912 and the idle-roller Z920 in the position shown in Figs. 4 and 5. If the shifting gear C12 be thrown into mesh with the gear c11 on the countershaft c1, as should have been done before shifting the loose pulley 011 for turning the drum in the proper direction to work the butter, the central roller Z912 will re ceive a positive motion in the direction shown by the arrow. Then, under the rotary motion of the drum, the butter will be gathered and carried up by the drum and dropped from the cleats Z2 thereof onto the rollers Z220 Z211 Z912. Under the positive action of the roller Z212 the butter will then be thrown outward into engage ment with the idle-roller Z911, and the said rollers will thereby be turned toward each other.

The said rollers Z211 Z212 will therefore cooperate to work the butter through between the same and drop it back to the bottom of the drum. In this working action the covers Z91S for the radial arms Z910 of the crank-like hangers serve as ho pper-like end boards to deflect the butter inward as delivered from the drum-cleats and IOO IIO

direct the saine onto the Working rollers. The idle-roller h2 serves as a catch and feed roller for preventing the butter from falling back to the Wrong side of the Working roller Z212. After the butter has been Worked to the desired extent the gear c12 should be shifted outward, so as to thror the working roller Z712 out of gear with the drive from the countershaft, and the drum be given three or four more turns before stopping the same. Vhen the roller Z912 is thus thrown out of gear, all of the said internal rollers b i312 b2@ Will become idle and will stand stationary. Hence, under the continued rotation of the drum, from the countershaft or in the Working direction, all the butter will be carried up by the drum and collected onto the top of the said rollers b 1912 i320. On then rotating the drum until the door h4 thereof is directly in front of the roller b or slightly above the same all of the butter will be readily accessible for removal from the churn.

From the foregoing description it Will be seen that my machine is provided with an interchangeable speed-and-power gearing for rotating the drum relatively fast in one direction for churning and relatively slow, but with increased power, in the opposite direction for working the butter; and the said machine is also provided With an extremelysimple construction for operating the central member of the ivorkingrollers with a positive action.

Of course it will be understood that minor changes might be made in the details of construction Without departing from the spirit of my invention.

Because of the peculiar interchangeable speed-andpower drive described and the angular adjustment of the crank-like hangers b9 Z910 to opposite sides of the druin-axis, this machine may be belted to a line-shaft running in any direction, which is a great convenience for adaptation to different situations as to floor-space.
